Blade Wolf

Bladewolf also know as IF LQ-84i Prototype and known also as K-9000, is an A.I. who Raiden encounters in Metal Gear Rising Revengeance. Unlike the generic model Fenrir UGs, Bladewolf's A.I. is advanced enough to allow it human speech. Bladewolf comes with a chainsaw attached to its back, a supply of HF knives, and extedable claws. It's tail is used like an arm similar to that of Gekkos.

NOTE: This video contains strategies for completing the boss fight with an 'S' ranking on the Revengeance difficulty. It makes use of the Infinite Wig B (unlocking infinite FC to allow unending Blade Mode or Ripper Mode) to cut down on the length of each battle. The strategies shown here can be performed without using the wig, though the fight will last longer.

LQ-841 is probably the first challenge you will face (especially if you are playing it the first time). Remember that Parrying is more or less "screen oriented" as Raiden moves in the direction you push on your joystick (or directional movement button).

That said, move in the direction an attack is coming from while timing your parry in anticipation of the attack.

If at all possible perform parries up close so that you can quickly counterattack with a combo. Another opening you can exploit is immediately after a missed attack from the beast so it is imperative to not wander off too far when dodging. You can also try luring it toward the burning vehicles and hope that the wolf rams into them and damages itself in the resulting explosion. When you hear the line "I will obliterate your conciousness", it means that the beast is preparing for a takedown which is perhaps its strongest attack. At this point, get as far away from it as you can with Ninja Run and jumps. The lock on button is also your friend.

You might also want to equip Repair Nanopastes so that it gets used automatically when needed. You can replenish your supply by destroying the crates scattered around the area. Blade Wolf also has the capability to call for backup which include three regular cyborgs and a Gekko.
